What generation is this? My MP is the generation that came out in early 2008 with 2.8/3.0/3.2 processors. I usually have 4 Hitachi 750gb drives though one is temporarily removed. I also have the NVidia Quadro FX 5600 and an ATI Radeon 2600 video cards in the machine. And 16GB of RAM. It is not lightly outfit. I never have this happen with the fans even when the all 8 cores are busy for an extended period. My older G5 does howl like a Banshee when it picks up the load but this one always has a low rumble of HD and fans spinning at low speed. Are your dust filters full and it is not pulling good air through? Is the inside coated with dust and not giving off heat well? Until a few weeks ago it was in my basement apt, which is quite cold but not below 0C (10C or less) but is now in the upstairs office where it stays around 15-19C during the winter (we keep the heat turned down to 66F during the day and 60F at night).
